Asking a complete stranger if you can take their picture can be pretty scary. Maybe it’s a fear of rejection imagining all the terrible things they might say, but in reality the fear is usually worse than the actual rejection itself. If someone refuses then it’s usually just a polite, ‘No thanks’. I’ve never encountered anybody who was angry or annoyed by me asking. I still feel nervous sometimes, but the more you do it the easier it gets. A surprising fact is that a lot of people will actually say yes (about 90 per cent).
